p Specification of Letters Patent No. 10,823, dated April 25 1854.

principles of our said improvements by which our invention may be distinguished from others of a similar class, together with such parts as we claim and desire to have secured to use by Letters Patent.

The figures of the accompanying plate of drawings represent our improvements. Figure 1 is a plan ortop View of the machinery. Fig. 2 is a transverse vertical section of the same taken in the plane of the line A B, Fig. l.

Our improvements are made upon the machinery for which Letters Patent of the United States were granted to us bearing date the 28th day of February 1844 and fully described in the schedule annexed to the same,and consist first, in an arrangement of mechanical devices by which an extra twist can be given to the strands when desirable, so that the machine can be readily adapted for forming either soft or hard cordage as it is termed. We have also made an essential improvement in the movable crane for forming the rope into coils, as the end of the straight crane over which the cord passes, as described in the schedule above referred to, describes the arc of a circle,which we have found in practice prevents the coil from being perfectly formed. In lieu of a straight crane we use a bent crane with a hinged bar which moves parallel with the axis of the reel shaft, by which arrangement a perfect coil is insured.

We have further made an improvement by which the rope is stretched after it is formed and before it is woundinto a coil.

or a a in Fig. 1 represents the bobbins upon which the strands are wound, hung in the swinging frames 12, b, b, which have their journals in the plates 0 c-d (Z and are revolved by the shaft 6 e. The short cranks f, f, f which are attached to the ends of the journals of the swinging frames, have their journals in a plate or ring 9 g, which fits over and revolves upon the rollers h, h,

which have their bearings in a circular plate 2" (attached to the pulley kythe hollow shaft of which fits over anextension of the shaft e e; Motion is communicated to the shaft 6 e by a band on the pulley m, and when but1 one twist is to be given tothe strands, the plate 2' with its rollers is prevented from revolving, in any proper manner, so that the ring 9 ,9 will turn in one fixed circle of revolution, around the rollers h h it (held in one fixed position) and keep the bobbins a, a, a in a vertical position as they revolve around 1' a L f a E Q,

the shaftle e, in a similar manner as inthe machine first patented by us.

When an additional twist is to be the rope or hard cordage to be formed, the swinging frames instead of keeping the bobbins in a vertical position as they revolve around the shaft 6 e, are made to turn upon their axes while revolving around the said shaft, so as to give an extra twist to the strands, by causing the ring 9 g to revolve eccentrically around the shaft 6 e. This is eifected by means of the circular plate 6 to which the rollers '72,, lb, are attached, to which motion is communicated bymeans of given to a band n at extending around its pulley 7a,

the pulley 0 fixed to the shaft 6 e, and the grooved pulleys p, p, as shown in the drawings. The pulleys p 79 revolve loosely upon upright shafts g 9, so that by simply lifting the bobbin frames by the short cranks f, f, f.

The rope after being laid is drawn along by a system of gearing substantially similar to that described in the schedule before mentioned, and passes first around the pulleys 1" and s and thence around a pulley a forming a part of the first pulley r. The pulley t is oflarger diameter than the pulley s, which arrangement will strain or give a stretch to the rope. After the rope is thus stretched, it passes around the pulleys u, u, and the pulleys o, *v, o, c of the movable crane w, w m which I shall now proceed to describe, This crane consists of a straight bar w, hinged to a standard y and attached to a curved or bent arm to. To this arm 10 is attached an arm as turning on a pivot at y.

The arm 0:: extends over the winding reel 2 parallel with the axis of the same, so that as the reel revolves the rope will be drawn over the pulleys of the crane and fed along, as the helical curves of the coil'are formed, in a line parallel with the axis of the winding reel, which thus forms a regular and perfect coil. In the use of a straight crane the end over which the rope is fed to the reel describes the arc of a circle, so that the rope will be carried farther from the coil when at the center of the same than when at either end, which prevents it from being regularly wound.

Having thus described our improvements we shall state our claims as follows:

What we claim as our invention and desire to have secured to us by Letters Patent, is,

1. Adapting the machinery for forming both hard and soft cordage by means of the ring 9 so actuated by the circular plate 6 and its rollers, made to revolve or held stationary as above set forth, as to form an extra twist in therope when desirable, by 2 giving an additional revolution to the ,bobbin frames as above described.

2. We also claim our improvement in the movable crane, the same consisting in forming it of'a bent shape with the right angular 3 hinged arm operating as above described, so as to feed the rope in a direction parallel with the axis of the winding reel.

8'. WVe also claim stretching the rope after it is laid by means of the double pulley r, t 3 with grooves of different diameter as above set forth. V p H g STEPHEN BAZIN. JAMES A. BAZIN. Witnesses to signature of Stephen Bazin:
